PRESSURE YREGULATOR AND DISTRIBUTER.

SPECIFICATION formingpart of Letters Patent No. 240,549, dated April 26, 1881. Application ledOctober 11l 1880. (Model.)

To all whom it may concern:

Be it known that I, ETIENNE SALOMON, of the city and district of Montreal, in the Province of Quebec and Dominion of Canada, ma-

chinist, have invented certain new and useful Improvements in PressureBegulators and Distributers, of which the followin g is a specification.

These improvementsare fully set Aforth in io the following specification and accompanying drawing. l

My invention relates to anovel and automatic apparatus for regulating, distributing, and shutting od' compressed air or other gases 15 oriluids at any desired pressure. It is intended forthe use of chemists, druggists, grocers,'deal ers in liquors, (being adapted for use as a beerpump,) and for many other purposes. lts superiority over all other apparatus hitherto in zo use for the same purpose consists in its greater compactness, simplicity, efficiency, and economy.

My improved apparatus consists, essentially, of a reservoirof sufcientcapacity and capable of sustaining the greatest pressure of air or other lluid which may at any time be 'applied by means of an air-pump or otherwise. This is connected, by a pipe furnished with a regulating stop-cock or valve, to a vessel preferably of a cylindrical form, divided into two compartments by a diaphragm, on one side of whichv the'cylinder communicates with the reservoir, as before mentioned, and on the other,

y means of the distributing pipe or pipes, with the surface of the liquids, Src., contained in the easks, vats, or other vessels to be operated pon.

The subordinateparts of the mechanism, hereinafter to be described, connected with both 4o compartments, respectively, are so arranged that by their mutual action the varying pressure of the reservoir may be modified at pleasure with the utmost delicacy and precision, so asto pass into the distributing-pipes at any re- 4 5 quired degree.

The accompanying drawing represents avertical section of my complete apparatus, which will suffice to explain all its features.

,t Letter A represents the reservoir, which is 5o to be supplied, by means of an air-pump or otherwise through the inlet-pipe a, with air, gas, or other duid 'at a pressure sufficien tly high for `all purposes required; B, the regulatngchamber, preferably of a cylindrical forni, divided into two compartments, B and B', by the dia- 55 phragm C, one one side of which the pipe D, furnished with a stop-cock or valve, E, connects the chamber B with the reservoir A.

The cylinder B is bored out and fitted with an air-tight piston, F, whose rod b communi- 6o cates motion to a lever, `G, having its fulcrum or center of motion at c, and provided with an adjustable weight or counter-balance, H, which may be regulated by hand toany required degree. The lever Gr is connected, by means1 of 65 a'rod, d, to the stop-cock E, and this mechanism is so arranged that the motion of thepiston F will tend to open lor close the stop-cock or valve E at the same time that the motion of the piston F is controlled and regulated by 7o the position of the adjustableweight H. i

It will thus be seen that when the pressure in the cylinder B is such as to counterbalance the regulated pressure transmitted through the `lever Gto the piston F, the latter lwill remain in equilibrium and no motion of the parts will ensue. 0n the other hand, as soon as this equilibrium is disturbed by the reduction `of pressure in the reservoir or by increased'ordiminished iiow from the distributing-pipesuthe 8o piston will rise or fall, and thereby openor close (more or less) the regulating stop-cock or valve E. i f

A hole, c, in the cover of the cylinder B is provided for the purpose of admittingth'eex- 85 ternal air to the outer side of the pistonRfor f the purpose of relieving it from any pressure tending to interfere with its free action on the inner side. i l

The second division of the apparatus on the 9o other side of the diaphragm C consists ofthe l following or equivalent mechanism: A conical valve, f, is fitted air-tight to the outer surface of the diaphragm C concentric with the cylinder and having its stem projecting out- Wardly and adapted to pass through and to slide up and down in the diaphragm freely, but without lateral motion. A passage, g, is, however, provided in the stem immediately above the valve, to admit of the air passing roo freely between both sides of the diaphragm VVwhen the valve f is opened.

To the opposite endof the stem, which is suficiently long to admit ofl the requisite space in the cylinder B' for the distributing pipe or pipes J provided with suitable stop-cock h, is attached a rubber disk or washer, j, suitably protected by metallic plates, and forming an air-tight cover for the cylinder B', but capable of moving up and down with the valvef. It is pressed upward by a slight spiral spring, K, and downward by a similar though stronger spring, L, which may be regulated to any required degree of tension by a hue-threaded screwed plug, M, worked by a hand-wheel or key, N.I In connection with the plug M is an index or pointer, k, which is carried up and down .with the plug, and serves to regulate and indicate, by a graduated scale, Z, upon the outerv casin g of the spring L, the degree of ,tensionV onthespring, and consequently the de greel of pressure at which the air or other fluid. is allowed to pass through the distributing pipe or pipes J.

The'action of the entire apparatus is as follows: When thepressurein the cylinderB from thev reservoir A is such as to counterbalancethe adjustable weight H, the spring L .being also set to the required pressure, the air or other gas from the cylinder B passes freely through ,the valve f and passage g into the regulatingfchamber B', thereby raising the rubberwasherj and closing the valve f when the pressure inboth compartments B and B' are equal. The efflux of the airor other, luid through the distributing-pipe J will reduce the pressure in the cylinders B and B', which, through the action of the piston F, will cause thecounter-balance H to descend, thereby opening the stop-cock or valve E to admitl a further supply of air at an increased pressure from `the reservoir A.y At the same time the spring L, pressing upon the movable rubber washer or elastic diaphragm j, opens thevalve f, thusy equalizing the pressure on bothsides of the diaphragm C, the small springK tending to counteract any undue pressure from-thespringvL. Thus, when the in dex 7c points to zero there will be no pressure on the spring L. Consequently the small spring K will close the valvef, there being then no pressure either yin the chamber B or B'. On the other hand,

when the index is set at 10, as in the drawing, thecounter-balance H being also adjusted to the same iigure, a pressure of ten pounds on the square inch will be constantly and regularly maintained in the distributing-pipe J, notwithstanding any variation within reasonable limits of the pressure in the reservoir A.

Byappl ying another distributing-pipe, J', to the iirst compartment, B, and adjusting the weight H accordingly, two different degrees of pressure may be obtained at one andthe same time.

Having thus -fully described the nature and operationof my invention, what I claim` as new, and desire to secure by Letters Patent is as follows, viz

l. In combination with a reservoir containing air or other gas or iiuid under pressure, a regulating-chamber divided into two compartments by an air-tight diaphragm or partition having an intermediate regulating-valve, one being connected with the supply and the other with the distribution, each compartment being provided with a movable air-tight piston or elastic disk or washer, both of which are capable of being regulated by adjustable weights or springs to any required degree, one actuating the supply and the other the distribution valve or stop-cock, by the mutual action of which the pressure may be regulated, distrib. uted, orshut oft' at pleasure.

2. The combination of the chamber B, divided into two compartments, B and B', by an air-tight partition, G, as specified, with the `piston vF or movable air-tight disk or washer,

adjustably-weighted lever Gr or spring press- -ing the piston inwardly with any required degree of pressure, the connecting-rod d, actuating the stop-cock or valve E, the valve f, passage g, springs K and L, or their equivalent,

4capable of exerting a regulated pressure upon the valve f, elastic air-tight washer or piston v j, screwed plug M, index 7c, and graduated scale Z, all relatively arranged and operating With the reservoir A and distributing pipe. or pipes J J', substantially as and for the purposes specified.
